The results of the research showed that the direct survey of condensation with the new sensor is more accurate and reliable than the traditional indirect microclimatic measurements. Since the construction of the first prototype, the dew sensor was developed further, continuously improved, validated in the laboratory and applied successfully on different surfaces at sites of interest in the field of Cultural Heritage; on the stained glass windows in the Saint Urbain Basilica of Troyes （France）, Sainte Chapelle of Paris （France） and Cologne Cathedral （Germany）; on stone walls in Petrarca＇s Tomb （Padua, Italy） and the Hagar Qim Temple （Malta）. Now the sensor is being used in the Lascaux Caves （France）. The newly built device was patented （PTC/EP2005/050665） and gave such interesting results that the Italian Ministry of University and Research financially supported a spin-off project that has lead to the creation of a new company （R.E.D.s.r.l.） in order to develop the prototype further and to produce the sensor at industrial scale.展开更多

The study included historic and archivist research, structural studies, mineralogical analyses, biological sampling, cleaning tests and microclimatic monitoring. The main weathering factors and the related damage processes were identified. Results have shown that the main responsible for the observed damage was the infiltration of rainwater through the roof, due to cracks in the structure of the Cathedral. Other environmental factors having a remarkable impact on the state of conservation of the polychrome and its substrate were the solar radiation, the thermo-hygrometric cycles, the particle deposition and the biological growth. Solutions were suggested to improve the environmental conditions, thus reducing further damage.展开更多
